In his newest publication, Ralph concentrates on the history of Corrour Bothy. The book tells the story of the oldest and most famous bothy in the world, celebrating a century of public use in 2020. The book blends visitors' book entries with historical accounts. Through visitors' book entries between the years of 1928 and the present day, Ralph outlines bothy life, the history of the Highlands, of hillwalking and of climbing and thereby provides a portrait of the past 100 years from a unique perspective centred on the Cairngorms.
